I have 9900K on z390 Maximus xi code. two 2080ti cards. 
	This is a fresh install of Windows 10 (2014)   
	It can happen random times not under load, always ntkrnlmp.exe.  
	I use aida64extreme to run a beadapanel. 
	Turned off my overclocks upgraded my bios to Aug18 (1602). Now only xmpII to run the memory at 3600mhz.  
	This build of windows has been an absolute nightmare. I think they changed the way their kernel connects to the hardware, I don't know not a coder, just a philosopher. I have come to that conclusion cause none of the drivers work right, Nvidia had to make a hot fix version, and even with Chipset drivers the bios sends too much info to windows and there is an event viewer. 
	Like I said a nightmare, I don't understand why it's not more known, unless everyone is still on 1909.
